Beta 2 for WordPress 4.2 is out. If you don't already have trunk running somewhere, you might consider running the beta tester plugin so you can give it a spin.
Press This has continued to get a lot of attention, and I found something wonderful about it today; if you open it from the “new tab” screen, it doesn't pick up a URL and it actually makes a beautiful easy to access post editor, with no fluff. I seriously love it and will probably use it for my personal blog as the default edit screen.
Nevertheless, over 70 changes went into the release and we're getting ever closer. Check out what's new and get testing!
